团队开发冲刺第十三天（完成带历史记录的搜索框）

今天完成的是带历史记录的搜索框

　　利用的是一个集成好的框架，一个带历史记录的框架。首先在主界面设置一个搜索的按钮，点击后来到全局搜索的布局页面，然后输入搜索的关键字， 点击搜索就会出现对应的文章，点击任意文章后就会看到相应的博文。

　　SearchActivity

package com.example.newbsh.UI.Find;

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;

import android.os.Bundle;

import scut.carson_ho.searchview.ICallBack;

import scut.carson_ho.searchview.SearchView;

import scut.carson_ho.searchview.bCallBack;

import com.example.newbsh.R;

public class SearchActivity extends AppCompatActivity {

private SearchView searchView;

public static String text;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_search);

// 3. 绑定组件

searchView = (SearchView) findViewById(R.id.search_view);

// 4. 设置点击搜索按键后的操作（通过回调接口）

// 参数 = 搜索框输入的内容

searchView.setOnClickSearch(new ICallBack() {

@Override

public void SearchAciton(String string) {

text=string;

Intent intent=new Intent(SearchActivity.this,FindActivity.class);

startActivity(intent);

//finish();

}

});

// 5. 设置点击返回按键后的操作（通过回调接口）

searchView.setOnClickBack(new bCallBack() {

@Override

public void BackAciton() {

finish();

}

});

}

public static String getText() {

return text;

}

}

FindActivity

setContentView(R.layout.activity_find);

title=SearchActivity.getText();

jsonArray=new JSONArray();

getThreadData();

handler = new Handler(new Handler.Callback() {

@Override

public boolean handleMessage(@NonNull Message msg) { //线程回调更新数据

if (msg.what == 200) {

jsonArray = ((JSONArray) msg.obj);

Log.e("输出jsonarray", "onCreate: "+jsonArray );

findAdapter=new FindAdapter(jsonArray,FindActivity.this);

listView=(ListView) findViewById(R.id.listviewlike);

listView.setAdapter(findAdapter);

}

return true;

}

});

}

private void getThreadData() { //线程封装网络请求

new Thread(new Runnable() {

@Override

String reqdata = "";

String address="http://39.97.181.86/BaiXiaoSheng/findlike?title="+title;

try {

final JSONArray json = new JSONArray(String.valueOf(HttpUtil.sendPost(address, reqdata)));

Log.d("tag", json.toString());

Message msg = new Message();

msg.obj = json;

handler.sendMessage(msg);
